Question

How do atoms achieve noble-gas configurations in single covalent bonds

Answer 1

by sharing an electron

Step-by-step explanation:

each of the two bonded atoms share an electron....making a single covalent bond b/w the two....like in....F - F

Answer 2

Elements forming covalent compounds achieve noble gas configuration by sharing electrons within the atoms, unlike ionic compounds which achieve the noble gas configuration either by gaining or losing electrons from the outermost electron shell.
